\noindent {\bf Problem statement} Suppose $f(x)=e^{\scriptstyle
-{ 1/  x}}$.  Graph this
function in the window $-5\le x\le 5$ and $0\le y \le 10$. Find the
line tangent to $y=f(x)$ when $x=2$ and include it in your graph. Also
find any horizontal or vertical asymptotes and include them in your
graph. Give explanations of the asymptotic behavior. Does the graph
have any inflection points?
